The benefits of a glycolic peel 30% concentration are to improve skin tone, decrease the size of pores and give a healthier glow to your skin. Since glycolic peels are mild, they are best used to treat surface imperfections. This concentration is great for beginning diy peel users and the peeling agent is also safe to use on all skin types and there is no downtime or heavy peeling to deal with. However, since these peels are superficial and only penetrate the outermost layer of your skin, you will need a series of treatments to see significant results, but they can be a great maintenance tool to keep your skin looking good after you’ve had a deeper peel.
